The spa It’s an enchantingly Robinson Crusoe affair, set in jungle seconds away from the white-sand crescent of Ninh Van Bay, near Nha Trang, southern Vietnam. You get around the Six Senses resort by butler-driven buggy – or pedal power.

Spa Spy’s symptoms A super-tight upper back, neck and right shoulder, triggered by computer use, plus nerve-tingling down the right arm. Even after a week of holiday, Spy couldn’t relax her right upper body.

The prescription A Thai massage that focuses on body-stretching along energy channels, or meridians, to re-awaken the body’s energy flow.

The procedure Spy was asked to change into loose cotton pyjamas for the 60-minute massage (£60). A therapist was soon expertly walking over her. It wasn’t for the faint-hearted: just as she thought she couldn’t be stretched further, the therapist did precisely that.

The verdict Afterwards Spy felt a profound release in the problem area, and the tingling tightness had gone. She felt a foot taller.

The medical opinion “Massage is a great option for relieving muscle tension,” says Dr Rupal Shah. “A more long-term solution is likely to involve physiotherapy or exercises for core stability, such as Pilates or Alexander Technique.”

The feel-good factor The resort is accessible only by boat, on the kind of palm-fringed beach of which dreams are made. Accommodation is in quirky yet luxurious villas. Food in the two restaurants is fresh and fabulous.
